Description

Technical Field

[0001] The utility model relates to the field of connector shells, and more specifically, to a spliced ​​coaxial connector shell. Background Art

[0002] The main functions of the connector include providing mechanical support and protection, ensuring the safety and stability of the internal connection structure, and playing a good electromagnetic shielding role, effectively reducing signal interference and attenuation. Its structural design is sophisticated, including the port for connecting the cable and the interface for docking with other connectors, which can ensure precise matching with other components. It is widely used in many fields such as communications, electronics, radio and television.

[0003] Connectors are mainly used to connect two active devices. After connection, they can transmit current or electrical signals.

[0004] The coaxial connector shells currently used are mostly of an integrated design. During the process of welding and connecting the connector shells, the entire connector shell needs to be involved. This method has the problem that when the processing fails, the entire shell needs to be scrapped, which easily causes a waste of production resources. In view of the above shortcomings, some connector shells are divided into two parts, namely an inner shell and an outer shell, which can be produced separately to avoid overall scrapping. However, the inner shell and the outer shell are fixed by using an interference fit, which makes it inconvenient to replace a single shell when damaged (the two are not convenient to disassemble).

[0005] Therefore, in order to solve the above technical problems, the present application proposes a spliced ​​coaxial connector housing. Utility Model Content

[0014] Preferably, the inner edge of the circular through groove is rounded, and the end of the connector inner shell passes through the circular through groove and contacts the surface of the circular through groove, thereby assisting the connector inner shell to pass through the circular through groove more smoothly.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Before the inner housing of the auxiliary connector passes through the circular through groove, the utility model pulls the annular plates on both sides to move to both sides, and the annular plates drive the movement of the inner plate through the connecting rod A.

DETAILED DESCRIPTION

[0030] like Figure 1-7 As shown, the utility model provides a spliced ​​coaxial connector shell, including a connector shell 1, a connecting chamber 2 is provided inside the connector shell 1, a detachable connector inner shell 3 is sleeved in the connecting chamber 2, an end of the connecting chamber 2 passes through the connector shell 1 to form a circular through groove 11 for the end of the connector inner shell 3 to pass through, annular grooves 4 are provided on both sides of the end of the connector inner shell 3, elastic components 5 are provided on both sides of the surface of the connector shell 1 for driving the annular plate 6 to move toward the middle part and insert into the annular groove 4, the connecting chamber 2 is designed in three sections to form three groups of sequentially descending grooves, the middle part of the connector inner shell 3 conflicts with the middle groove, the material of the connector shell 1 is metallic copper, and the material of the connector inner shell 3 is copper-zinc alloy.

[0031] The elastic component 5 includes a hollow shell 51 installed on the surface of the connector outer shell 1, and cylindrical rods 52 are fixedly connected to the two sides of the interior of the hollow shell 51. An inner plate 53 is slidably connected to the interior of the hollow shell 51, and a through hole A54 is opened inside the inner plate 53 for the cylindrical rod 52 to pass through. The outer wall of the cylindrical rod 52 is located on both sides of the inner plate 53 and is fixedly connected with a spring 55, and one end of the spring 55 is fixed to the surface of the inner plate 53, and the other end is fixed to the inner surface of the hollow shell 51. The surface of the inner plate 53 is fixed to the annular plate 6 through a connecting rod A56, and a through groove A57 is opened on the side of the hollow shell 51 opposite to the connector inner shell 3 for the connecting rod A56 to pass through.

[0032] The model of the connector shell is 4.3 / 10-KYB3. The connection chamber 2 is designed in three sections to form three groups of sequentially descending grooves. The middle part of the connector inner shell 3 conflicts with the middle groove, which is used for axial positioning of the setting position of the connector inner shell 3. When the connector inner shell 3 conflicts with the middle groove of the connection chamber 2, the connector inner shell 3 is installed in place relative to the connector outer shell 1. The middle section of the connector inner shell 3 can play an axial positioning role in the installation of the insulator to ensure that the insulator can be installed in place. At this time, the end of the connector inner shell 3 also passes through the circular through groove 11 on the connector outer shell 1. The inner edge of the circular through groove 11 is rounded. The circular through groove 11 with rounded corners can be used to guide the connector inner shell 3 when it enters, and assist the connector inner shell 3 to pass through the circular through groove 11 more smoothly. Before passing through, pull the annular plates 6 on both sides to move to both sides, and the annular plates 6 pass through The connecting rod A56 drives the movement of the inner plate 53, and the inner plate 53 moves linearly along the cylindrical rod 52 through the through hole A54 thereon, while squeezing or stretching the springs 55 on both sides thereof. After the connector inner housing 3 is inserted into the circular through groove 11, the annular plates 6 on both sides are loosened, and the springs 55 begin to reset, thereby driving the annular plates 6 to move toward the middle part and inserting them into the annular groove 4 on the connector inner housing 3 to achieve the fixation of the connector outer housing 1 and the connector inner housing 3. Similarly, the two annular plates 6 are pulled to both sides again to pull them out of the annular groove 4 (the annular groove 4 is set according to the corresponding design made according to the cylindrical end of the connector inner housing 3, without changing the shape of the end, and can be well adapted to the connector inner housing 3), so as to realize the disassembly of the connector outer housing 1 and the connector inner housing 3, and the operation is very simple, so that a single housing can be easily replaced when damaged.

[0033] In addition, the connector outer shell 1 and the connector inner shell 3 of the utility model are made of different materials. The connector outer shell 1 is copper-zinc alloy, and the connector inner shell 3 is metallic copper. Different from the current one-piece connector shell design, it can reduce the use of copper and reduce production costs. At the same time, the splicing design also avoids the problem of scrapping the entire connector when processing fails.

[0034] Furthermore, a connecting rod B58 is fixedly connected to the surface of the inner plate 53 opposite to the connecting rod A56, and a through groove B59 for the connecting rod B58 to pass through is opened on the other side of the hollow shell 51, and a handle 510 is fixedly connected to the head of the connecting rod B58, so that the inner plate 53 can be pulled to move to both sides by the handle 510, and the inner plate 53 pulls the annular plate 6 to move to both sides, which makes it more convenient for the staff to pull the annular plate 6.

[0035] As a further improvement, the hollow shell 51 is detachably connected to the connector outer shell 1, so that when the elastic component 5 is damaged, it can also be replaced. The bottom end of the hollow shell 51 is fixedly connected with a lower opening groove seat 7, and protrusions 8 corresponding to the lower opening groove seat 7 are welded on both sides of the surface of the connector inner shell 3. The side ends of the protrusions 8 are provided with screw holes 9, and the side ends of the lower opening groove seat 7 are provided with through holes B10. That is, when installing the elastic component 5, the lower opening groove seat 7 below the hollow shell 51 is inserted into the protrusion 8. After the insertion is completed, the screw hole 9 and the through hole B10 are aligned. Then, the screw is passed through the through hole B10 on the lower opening groove seat 7, and then rotated clockwise to install it into the screw hole 9 on the protrusion 8, so that the protrusion 8 and the lower opening groove seat 7 can be fixed, thereby completing the installation of the elastic component 5. Similarly, the screw can be turned counterclockwise to remove the screw, and then the lower opening groove seat 7 can be pulled off from the protrusion 8 to complete the disassembly of the elastic component 5. The disassembly and assembly are very convenient.
